DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent-No.,351,9l7, dated November 2, 1886.

Application filed September 1ll 18%. Serial No. 213,309. (No model.)

To aZZ whom t may concern,.-

Be it known that I, CIIARLEsF. HoLcK, of

Laporte City, in the county of Black Hawkv of, in whichf and through the end of the equalizer.

y Figure 1 is a plan view of my improved draft-equalizer, and Fig. 2 is a side sectional elevation of the same, the section being taken on line x w of Fig. 1.

Similar letters of reference indicate corresponding parts in both views.

The object of my invention is to provide a `simple and efficient draft-'equalizer i or use with four horses abreast. Y

AMy invention consistsr in a novel Iarrangement of equalizing-bars, the draft-equalizing chain extending over a sheave journaled in the frame attached to the tongue, and in novel devices for. supporting the pivots of the equalizing-levers, all as hereinafter more fully described.

To the tongue A are secured the bars a b,

the bar a projecting from the tongue at right angles, and the bar b connecting the outer end of the bar a to the `tongue A at a point between the said bar a and the fastening of the tongue. Upon the bolt c, which connects the outer ends of the bars a b, is pivoted one end of the equalizing-bar B, the said equalizingbar extending beneath the tongue.

To the under surface of the equalizingbar B, atthe free end thereof, is pivoted an equalarmed evener, C, carrying at opposite ends single-trees D, that are connected with the evener by straps d.

To the tongue A, a short distance in front of the bar a, are pivotally connected two bars, e f, by the bolt g. .i These bars extend rearwardly, and between their rear ends is pivoted one end of an equalizing-bar, E, upon the bolt h, passing through 'the ends of the bars .e In the middle of the equalizer-bar E is inserted an eyebolt, ,which isconnected by a chain, j, with a similar eyebolt,t', in the middle of the equalizer-bar B. The chain j extends around the sheave k, journaled in a frame, Z, secured 5o to the under surface of thetongue A near its rear end. To the outer end of the equalizerbar E is pi voted the eve-ner C,whose ends are connected by straps cl with single-trees D. Upon the bolt g is placed a clevis, m,which is connected by a chain, n,with a clevis, o, on the bolt h, which connects the bars e f and the equalizer-bar E. A rod, p, connected with a ring, q, encircling the forward end of the tongue, is attached to the chain n and clevis mby the ringr. This arrangement of the rod p, clevis m, and chain a limits the rearward swing of the bars ef and fixes the position of the inner end of the equalizer-bar E.

llhe horses hitched to the single-trees Dare placed on opposite sides ofthe tongue A, and the draft, through the medium of the equalizing-lever B, the chain j, and the equalizinglever E, is opposed tothe draft of the horses hitched on the single-trees D. By means of 7o my improvedA arrangement of equalizing bars and chains I am enabled tosecurea thorough equalization of the pull ofthe four horses,and` to a great extent to avoid side draft;

When it is desired to apply my improve- V ment to plows and similar utensils, the sheave k is removed to some portion of the frame of the plow or implement at one side or the other of the tongue A, in accordance with the requirements of the work to be done.

YHaving thus fully described my invention, I claim as new and desire to secure byLetters Patent- Y v 1. In a draft-equalizer, the combination of the tongue A, provided with the bars a b, the equalizer B, pivoted at one end to the bars a b, the evener C, pivotally connected with the free end of the equalizer-bar B, the bars e f, connected with the tongue, the equalizer-bar E, pivotedbetween the bars e f, the evener C', carried by the free end of the equalizer-bar E, thechain j, connecting the equalizing-bars B E, the sheave k, for guiding the chain j,an d the single-treesD D', connected with the eveners C C', substantially asdescribed. 95

2. In a draft-equalizer, the combination of the tongue A, provided with the bars a b, the equalizer B, pivoted at one endfto the bars a I, the evencrC, pivotally connected with the j, the single-trees D D', connected with 'the free end of the equnlizerbar B, the bars e f, eveners C C, the clevis m, chain u, @levis o, connected with the tongue, the equalizer-bar and rod p, substantially as described.

E, pivoted bet-Ween the bars e f, the @vener CHARLES F. HOLCK. 5 C', carried by the free end of the equalizer- Vitncsses:

bar E, the chain j, connecting the equalizing- J. S. EBERHART,

bars B E, the sheave k, for guiding the chain I. JAMES.
